To SF Leong: Refering to EA 37(1)(bb), the number of ML exceeded 30 days in advance shall be regarded as no pay leaves. But you have the following options:
1) To deduct the salary of the number of ML exceeded 30 days in advance, and assume the maternity leaves have started on the 30th day in advance prior to the expected due date.
2) To get the expected mother's consent to have started the maternity leaves from the date she was on ML, and the 2 months maternity leaves are counted from that day on.
To Priscila: Yes, you are under the coverage of maternity leaves (60 days) by EA though it is not stated on your employment letter.
